  • Are people always browsing?  If so, the squid is always caching.

  • …and what about logging? That could also be causing frequent disk access.

    There are parts of the system that write periodically. Logs, gateway status, graphs, and several other things could be getting written to the disk, though it shouldn't be completely constant.

    If you run "top -aSH", press 'm' to switch to i/o view which will show you which active processes are writing/reading at the time. The normal top view is CPU only and wouldn't tell you much about the disk.
